The Threshold field specifies the disk space threshold. If a write causes the quota target to exceed the threshold, the write still succeeds, but a warning message is logged to the storage system console and an SNMP trap is generated. This field is optional.
The following list describes the rules for specifying a value in this field:
- K means 1,024 bytes, M means 2 to the 20th power or 1024 * 1024 bytes, and G means 2 to the 30th power or 1024 * 1024 * 1024 bytes.
Note: The Threshold field is not case-sensitive. Therefore, you can use K, k, M, m, G, or g.
- The maximum value you can enter in the Threshold field is one of the following values (roughly equivalent to 1,023 PB):
Note: If you omit the K, M, or G, Data ONTAP assumes a default value of K. The value cannot be specified in decimal notation.
- The value in the Threshold field, if any, should be a multiple of 4 KB.
If it is not, the Threshold field can appear incorrect in quota reports. This happens because the Threshold field is always rounded up to the nearest multiple of 4 KB to match disk space limits, which are translated into 4-KB disk blocks.
- The Threshold field must be on the same line as the Disk field.
Otherwise, the Threshold field is ignored.
- If you do not want to specify a threshold for the quota target, enter a hyphen (-) in this field or leave it blank.
